Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541164, here are decompositions:

3 + 31541161 = 31541164
23 + 31541141 = 31541164
47 + 31541117 = 31541164
113 + 31541051 = 31541164
173 + 31540991 = 31541164
293 + 31540871 = 31541164
521 + 31540643 = 31541164
821 + 31540343 = 31541164

Showing the first eight; more decompositions exist.
